MIOAJAH O. MALONE, OF PALMYRA, ILLINOIS, ASSIGNOR OF ONE-HALF TO PAUL B.SPOONER, OF SAME PLACE.

COMBINED METAL-SHEARS AND TlRE-UPSETTER.

SPECIFICATION forming part of Letters Patent No. 411,386, datedSeptember 17, 1889.

(No model.)

To all whom it may concern.-

Be it known that I, MIOAJAH O. MALONE, a citizen of the United States,residing at Palmyra, in the county of Macoupin and State of Illinois,have invented newand useful Improvements in Combined Metal-Shears andTire-Upsetters, of which the following is a specification.

My invention relates to improvements in combined metal-shears andtire-upsetters; and it consists in certain novel features hereinafterdescribed and claimed. In the ac coinpanying drawings, Figure 1 is aperspective view of my improved device, and Fig. 2 is a side view.

Referring to the drawings by letter, A designates the lower orstationary jaw of the shears provided with a downward extensionB,throughwhich the securing-bolts are passed into the work-bench tosecure the device in position, and having on its upper side at one endthe curved standard 0, which is provided on its outer side with thetransverse cogs or rack-teeth D, as shown. At the end of the stationaryjaw, opposite that end at which the standard 0 is erected, I pivot theupper or swinging jaw E. This jaw E is provided at its outer end withthe bifurcation or fork F, which passes around the standard 0, and theoperating-lever G is pivoted between the ends of this fork orbifurcation. The inner end of the operating-lever is provided with asegmental rack-bar II, which engages the teeth of the standard 0, sothat when the said lever is vibrated it will be caused to move up ordown on the said standard and to raise or lower the swinging jaw. Thejaws A E are provided in their adjacent edges with the longitudinalrecesses I, and the knives J are secured in said recesses.

The jaw A is provided in its outer side with a recess K, which forms acontinuation of a similar recess or groove L in the extension B, and thesaid jaw and extension are provided with the outwardly-projecting rib Malong one side of said recess. The upper jaw is provided with an offsetN, which is adapted when the jaws are brought together to lie directlyover the recess K, and is provided at its edge with the lateralprojecting rib or plate 0, forming practically a continuation of the ribN. In the upperend of the offset K and the lower end of the extension B,I secure the plates P, which are provided with teeth Q in their outerfaces, and directly over said plates I pivot to the ribs M and O thecamlevers R, which are provided in their inner edges with the transverseteeth S, as shown.

From the foregoing description the operation and. advantages of mydevice will be ap parent. When it is desired to divide a bar of iron orother metal, the bar is inserted between the jaws and theoperating-lever then lowered, thus bringing the upper jaw down upon thebar with a positive and strong press ure, so as to sever the same. lVhenit is desired to upset a tire, the tire is clamped in the recesses K andL and against the offset N by the cam-levers B. being turned so as tocause the teeth S to bite against the tire and so secure it in positionto be operated upon. The superfluous length of tire can then be readilyshrunk to make the tire fit tightly around the wheel.

My device is very compact in its arrangement, and by its use I amenabled to cut heavy metal bars with very little labor, as theconstruction of the standard and the operating-lever moving thereoncause the upper jaw to exert a very powerful pressure against the lowerjaw. The knives are removably secured to the jaw, so that they can beeasily detached to be sharpened.

\Vhen it is desired to cut a tire or band, the operating-lever G andswinging jaw E are raised above the standard 0, when the tire or bandcan be placed between the jaws A and E. ,Then by lowering the lever Gsaid tire or band can be readily severed.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination of the stationary jaw having the standard O erectedat one end and provided with the transverse teeth D, the swinging jawpivoted to the stationary jaw and having a bifurcation at its free endpassing around the standard, and the operatinglever pivoted in saidbifurcation and provided at its end with the segmental rack-bar engagingthe teeth on the standard, as set forth. a

2. The combination of the stationary jaw having the downward extensionB, the upper jaw pivoted to the stationary jaws and having an oifset N,the ribs M O, secured to the extension B and the offset N, respectively,and the cam-levers pivoted on said ribs, as set forth.

3. The combination of the stationary jaw having the recess K, and thedownward extension B, provided with the recess L, forming a continuationof the recess K, the upper jaw pivoted to the stationary jaw and havingan ofiset N, the ribs M O, and the cam-levers pivoted to said ribs andhaving teeth in their edges, as set forth.

4. The combined shears and tire-npsetter comprising the stationary jaw,the standard 0, erected at one end of the same and having the transverseteeth E, the extension B, depending from the stationary jaw, the movingjaw pivoted to the stationary jaw and having a bifurcationat its freeend passing around the standard O, the lever pivoted in said bifurcationand having a segmental rack bar engaging the teeth of the standard 0,the offset N on the swinging jaw, the ribs M O on the extension B andthe offset N, respectively, the plates P, secured in the ends of thesaid extension and offset, and the cam-levers pivoted to the ribs abovesaid plates, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
